- Application filed January 13.1902- S rial lit-89.4119- To all-whom it may concern:

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain.

new and useful Improvements in Typographic Machines, of which the following is a' by -rotating or oscillating members, and is principallyintended to provide an improved synchronizing device by means of which a certain sequential and specific relation of device, to the each type, typs-punch or other irn ression eyboard and trains 0' selective-mechanism, is established, subsequently to each operation of said impression device,

A in order to efiect, with certainty, the opera tion of any desired one of the latter, by

means. of its. correlative key. The relative sit'ion of the impression devices estabished by the synchronizing device, as aforesaid, wi1l, hereinafter, for convenience, be referred to as zero, and the impression devices as types.

Another important feature of my inventionconsists in the improved form of the selective mechanism shown herein, whereby a the operation of any key results, withcer tainty, in the presentationof its correlative type in the roper position for obtaining an impression t ereof.- he mechanism 0 crating the turret has been made, by me,' t e subject of a separate application for Letters Patent, patented March 2.9, 1906, No. 815,979.

In the drawings relating hereto, Figure 1 is a longitudinal vertical view, )artly' in elevation and partly in section, s owing all of this invention exce t a portionofi the selective mechanism;- t e section being taken through the median lineac-sc, Figs. 2, 3, 4, and 5 Fig. 2 is a top plan view of the whole series of trains of-selective mechanism; the trackers, latches and s rings thereof being shown only in dotted lines; Fig. 3 is a top lan view on a larger scale, of alatch plate, atches, frictional springs, trackers, bell cranks, ,etc., forming portions of the selective I trains of mechanism; Fi 3 is a modification of a'selective traim Fig. 4 is a top plan tial top plan view of the drivirig and turretrotating mechanisms, the synchronizer-operating levers and other parts; Fig. 6 is a perspective view, partly in section, of the synchronizing' mechanism at the commence ment of its functional movement; Fig. 7 is a similar view of the same, with. the synchronizing movement completed, and Fig. 8 is a rear elevation of the synchronizer actuator.

. The references are relatively alike throughou-t'the drawings A, A, is a case inclosing a major portion; oi the machine and serving as a mount for parts of the mechanism. Keys 1, 1, are suitably mounted in a keyboard B, and severally attachedto the'key-levers 2, 2, fulcrumedat .2,

2. Links 4, 4, are severally pivotally' attached, at their upper ends, tothe ends of the key-levers 2-, 2, and, at their lower ends, to bell-crank levers 4, 4, fulcrumed on suitable sup orts, and having their lower ends .sevy 'eraly pivotally connected to trackers 5, 5,

Springs 3, 3, severally serve to maintain the keys 1, 1, key-levers 2, 2, bell-cranks 4, 4, and trackers 5, 5, in their zero, or non-operative, positions.

The trackers 5, 5, are forked at their inner endwhere they severally loosely embrace the outer ends of latches 6, 6, which are re-- ciprocatably mounted in-the latch block C, Figs. 2 and, 3, and are severally frictionally engaged by the latch springs 6, 6. The trackers 5,5, and latches 6, 6., are curved, in order to enable proper connections to be established between the bell-cranks 4, 4, and the latches 6, 6, while maintaining, in the latter, the form required to insure their proper and uniform operation, as hereinafter set forth. Several of the latches 6, 6, as shown in plan view at a, a, a, Fig. 3, and in elevation 1n.Fig. 3, are operated without intervention of trackers, their positions relative to the keyboard B, rendering this plan feasible; the outer ends of the latches 6, 6, being severallloosely engaged by the lower ends of the be l-cranks 4, 4. Y Rotatably mounted on a fixed vertical pivot D, Figs. 1, 2 and 5,.and further supported by a conical journal fa-t its upper end, is aturret E, carrying, as shown, two rotating shafts S, 8, parallel with said pivot D, and each carrying on itadower portion a mounted thereon, the rotation of said sleeves 9, 9, on the shafts S, 8, being prevented by the splines 8', 8, respectively. Frictional contact, by means not shown, but regulated by the screws 9 9, serves to maintain the sleeves 9, 9, in any vertical position in which they may be placed. on the shafts 8, 8. Collars 8 S' /at the lower ends of the shafts 8,

8, serve to retain the sleeves 9, 9, on said shafts. jecting tappet 9 so disposed that when in 10 its zero, or non-operative position, it may be engaged by the inner end of any one of the latches 6, 6, that may be so operated as to then intercept said tappet 9 when the turret E'is rotated. At the u per end of each sleeve 9, is a spur gear wheel 9, to the underside of which is rigidly attached one end of an elevator 9 preferably made in the form of a spring, as shown, the free end of the latter being recurved in the form of .a flat-faced bevel. The elevators 9, partly encircle the sleeves 9, 9. At the lower end of each sleeve 9, and integral therewith, is a radial flange 9; The latclnplate F, Figs. 1., 2,3 and 5, is secured to the case A. An annulus G,having depending bracket arms G G, furnished with lugs, is secured by thelatter to the upper surface of the latclnplate F. To the in terior surface of the annulus G, 1mm ov ably attached the internal gear segment 9, and concentrically therewith and below the annulus G, is suspended a curved. angle-plate 9 Fig. 1, one member of whicli projects in wardly and. is beveled, at the inner part, to a knife edge 9 which lies slightly below the plane of rotation of the free ends of the elevators 9 9.

A, is pivotally bracketedn bell-cranl-t-lever 11, one arm of which is arranged to engage the upper surface of either of the radial flangr-s 9 when the turret E is rotated; the

other; arm of said lever fl being pivotally attached to a link H, which. is slotted'at'its maposite end and embraces a drive shaft mpon which is mounted a cam H which, by

means of a cam-rollcr 7& reciprocates the link 11. The train of selective mechanism, thus described, is operated as follows:'-A key 1,

being depressed, elevates the inner end of its lever 2, and operates the connected bell crank 4; the depending arm of the latter forces forward the connected tracker '5, which sinnlarly operates a latch 6, so as to cause its inner endv to lie in the path of the.

tappets 9, 9", when their respective typewheel shafts 8, 8, are at zero and the turret E, is-rotated the direction of rotation of the latter being left-handed, or from north to West. The key 1, key-lever 2, bell-crank 3, and tracker-4, are all returned to their zero positions by a spring 3; but the latch,6, re-

mains in position, being frictionally retained there by its spring 6, and engages thenearest a preaching .tappet 9?,'partially rotates there ythe sleeve 9,.and also; by meansofa On each sleeve 9, is a radially-pro:

At the rear inside of the case spline 8, partially rotates a shaft 8, with all the parts mounted thereon. The partial rotation, as stated, of a sleeve 9, causes the beveled end of the elevator 9 mounted thereon to become engaged with the beveled edge of the curved angleplate g and, by the combined rotating and sliding motion of one inclined plane upon another, the sleeve 9, is elevated sufficiently to cause the gear-Wheel 9 to engage and mesh with the internal gear segments g; continued rotation of the turret E, thereby imparting an orbital rotation to the shaft 8, and all parts mounted thereon, including theimpression devices.

At the upper end of each shaft 8, and rigidly secured thereto, is a type-wheel 10, on the periphery of which is formed aseries of types, A, B, C, D, etc.; the term types,-

being generically used herein, to include all manner of designs of impression devices. The characters are similar on both type-- wheels 10, 10, and similarly disposed thereon, respectively, and are severally. represented on the keys 1, 1. -The before-described operation of'any key 1, and its train of selecting mechanism, results in the presentation of its cognate type at the common in'ipression point. The impression having been made, as hereinafter set forth, the cam H on the drive shaft H, draws forwardthe link 11, by means of the cam-roller h and 'so operates one arm of the bell-crank 11, that the other arni thereof depresses the flange 9 and the sleeve 9, moving the gear wheel 9" out of mesh from the internal gear segments 9, and. bringing the tappet 9*, again into the plane of the latches 6, 6. Each of the latches 6, 6, is returned to its zero point, after use, by means of a "final cam action of the end of the tap pet 9 which had been engaged by it. A spring 11', serves, by means of the bell crank 11 and link 11, to hold the cam roller 71,2 against the cam H and prevent backlash. in the connections of the )arts. H

The driving mechanism illustrated in the drawing, embodies a pulley K, a drive shaft H, mounted in the bearings L, L, and an actuator M, mounted on said shaft. The driven member of the mechanism is shown as a-roller turret N, mounted on a sleeve 0, which, with the fixed vertical pivot 1), forms the journal bearing for the turret E. The operation of the actuator M, with the roller turret N, is fully described in the prior application hereinbefore mentioned, and results in an intermittent rotary motion of the turret E, and all'part s mounted thereon; the cyclethereof being divided. into four unequal parts, as followsz-Namely, at each com plete revolution of the drive shaft H, the turret Eis rotated one-half of a revolution, at the end oflwhich there is a eriod of com plete rest; another half-revo ution and another period of rest completing the full cycle anism, depressing the sleeves 9 on the shaft '8, on which the operative type 18 mounted,

andv for synchronizing the opposite typewheel 10.

The synchronizing mechanism consists of cams .12, 12, Figs. 1, 6 and 7, rigidly secured ated by a cam H".

on the shafts 8, 8 the reciprocating camoperator13, carrying a knife-edged stud 13, and mounted in slideways 13 firmly secured to the frame of the machine; the duplexarmed, angular lever 14,.with the arms 14*, and 14, 14, fulcrumed on a horizontal fixed pivot P; a link.14 pivotally connected at one end to the short-arm'of the lever 14; the other-end thereof being slotted to embrace the drive shaft H, and a cam-roller k oper- Each cam 12, as shown herein, consists of two oppositely-spiral radial vanes meeting and joined at their lower extremities and forming a single radial knifeedge, their upper extremities being separated by a space sufficient to receive the knife-edged portion of the stud 13, on the cam operator 13.

The cam H", on the drive shaft H, is so designed as to o crate the synchronizing mechanism when t 1e turret E is at one of the two zero points at which the latter is at rest.

In operation, the turret E, being at rest, as aforesaid, and the shafts 8, 8, being in line with the knife-edge on the stud 13*, the cam H*, on the drive shaft H, by means of the cam-roller It", and the link 14*, moves forward, the arm 14 of the lever 14; thus raising'the arms 14", 14, of the latter, and by means thereof, .raising the cam-operator 13, with the stud 13", the knife-edged portion of the latter engaging, in its ascent, the cam 12, which is' on the shaft 8, which the immediately-precedent artial rotation'ofthe turret E, has broug it into the'proper relative position for such engagement; the further continuous movement of the cam-operator 13, partly rotates the cam 12, shaft 8, and

- type-wheel 10; the completion of the movement of the cam-operator 13, causing a-completc interposition of the knife-edged portion of the'stud 13 in the opening at the upper end of the dam 12, fixing the type-Wheel 10, and the sleeve 9, carrying a tappet 9F, and a gear-wheel 9 all in position for their proper operation by any one of the keys 1, and the train of selective mechanism to and including its correlative latch 6; Continued rotation of the'eam' H and-its operated train, depresses the cam-operator 13, c.al-

rying the stud 13, to a point below the rota; tory plane of'theca'ms 12, 12.,

The impressing, feeding and hiking mech-' anisms may be 0 any desired operative form,

I such, for instance, as shown,v where the former consists of an impressing cyllnder R,

and a feed roller E, Fig. 4, mounted ina carriage R; impressions being made by bringing the paper or other material mounted on the cylinder R, against the nearest type on a.

type-wheel 10, by means of a lever r, F1 8. 1,

4 and 5, oscillated on thefixed pivot ,by' means of a link 1*, cam-roller h, and the cam H on the drive shaft H. The inking devices, if used, may, in form, be as shown at S, S, Fig. 4; where spring-o erated levers S, S, hold the ink-rollers S, in position to engage the types A, B, C, etc, when the typewheels 10, 10, are rotated.
